http://www.foodfacts.info/blog/2008/08/burger-king-employee-takes-bath-in-sink.html This one. This thread is now about taking baths in fast-food restaurant sinks.
I don't see what the big deal is. It's not like someone bathing in a sink is going to permanently contaminate the sink and you can never again wash anything in it. They're washing dishes with scummy leftover food in scalding hot water with industrial detergent, and they're worried that the dishes won't get clean because someone bathed in the sink last night?
